WILLIAM THOMAS PEARCE, OF SOUTH MELBOURNE, VICTORIA.

COKING-OVEN, STEAM-CONDUIT CONNECTION, AND COOKING UTENSIL FOR USETHEREWITH.

SPECIFICATION formingpart of Letters Patent No. 669,221, dated March 5,1901.

Application filed January 8,1900.l Serial No. '763. (No model.)

To all whom, t may concern.-

Be it known that I, WILLIAM THOMAS PEARCE, oven manufacturer, a Britishsubject, and a resident of 116 Bank street, South Melbourne, in theColony of Victoria, have invented certain new and useful Improvements inCooking-Ovens, Steam-Conduit Connections, and Cooking Utensils to beUsed Therewith, of which the following is a speciication.

It is the object of my invention to provide asteaming attachment whichmay be secured to stoves and which will permit eatables being sotreated, while the ordinary baking and boiling of eatables on or in thestove are not impaired or interfered with.

To this end the invention comprises a boiler adapted to be suitablysecured to the front of a stove above the fire-chamber thereof, providedwith a heating compartment in direct communication with said chamber,the boiler having steam-outlets in the top thereof, and cooking utensilshaving improved pipe connections to said outlets.

The invention is illustrated in the accompanying drawings, in which-Figure 1 is a vertical sectional view through a stove, showing theboiler in place thereon and the cooking utensils connected thereto. Fig.2 is a plan view; Fig. 3, a front elevation of the boiler. Fig. dis adetail sectional view showing a cap in place.

The stove herein shown, which is supported on legs 1, has itsheating-chamber 2 located at the lower front end thereof. The oven 3,which is in direct communication with the hre-chamber, is provided witha detlector 4. and with the ordinary brackets 5, designed to supportremovable trays, which are not illust'rated in the present drawings. Theheated air passes below the de lector and th rough perforations in theback plate 6 of the oven into a rear flue formed between said plate andthe rear plate of the stove and up said iiue and over the top of theoven toward the front in a flue formed between the top plate of thestove and the top plate of the oven, around a short Vertical partition7, and is discharged through the rear of the upper flue.

The boiler attachment Sis substantially rectangular in shape, and it isdesigned to rest directly upon the top of the fire-chamber with its rearside forming the front wall of the oven. A (lange projecting upward fromthe rear upper corner of the boiler is bolted to the front plate of thestove to hold lhe boiler in place.

The boiler is intended ro be filled with water. To expose the greatestpossible space to the action of the fire, an air-space is formedcentrally of the rear part of the boiler, which is in directcommunication with the firechamber. This spaceis formed by providing inthe rear wall of' the boiler, centrally thereof, a recess 9, whichincreases in width toward the top of the boiler, but decreases in depth.The entire rear wall of the boiler is inclined from the bottom outwardlytoward the top, which presents a surface to intel'- rupt the ascendingheated air from chamber 2. The incline ofthe bottom of the recess issuch that it converges into the wall ot' the oven at the top of therecess. Thisair-space is open at its lower end directly into thefirechamber. 'Ihe top plate of the boiler is provided with threeopenings 10, surroumled by inner collars 11 and outer collars 12, ofgreater height than theinnercollars. An opening 13 is also provided inthe top, from which an open-ended funnel or tube depends into the boilerto a point below the desired mean water-level to be maintained therein.If the water falls below the lower end of the funnel or tube, steam willarise therethrough,

which will act as a warning that the water needs replenishing. As longas the Water in the boiler is above the bottom of the funnel or tube itwill be sealed againstA the egress of steam.

The cooking utensils are designed to rest directly upon the top of thestove, and they are provided with short spou ts with angular dependingends. A section of pipe 15 may be provided to connect each of the spoutswith the openings in the boiler-top. A pipe of this character isprovided with an angular depending end designed to fit between thecollars 11 and 12, and its opposite end is upturned and surrounded by acup-flange 17, designed to receive the end of the spout. The spacesformed between collars l1 and 12 and by f'lange 17 provide water sealsto prevent leakage of steam. The water which fills said spacesaccumulates from the condensation of steam'. Instead of IOO utilizingthe pipe-section l5 the spout may lit directly into the space betweenflanges ll and 12. The steam-outlets are covered by caps when they aredisconnected from the cooking vessel.

It is of great importance to the practical working of the stove thatmeans be provided to prevent the escape of steam from any of theopenings 10, which may be disconnected from a cooking vessel. To providea steamtight closure for these openings, caps, such as 20, are provided,which loosely lit collars 1l, the flanges of the cap depending into theliquid between collars 1l and l2. As the fit is a loose one, the cap maybe dropped in place without difiiculty as soon as a cooking vessel isdisconnected.

I claim- 1. The combination with a stove having an oven and aWater-heating compartment forming one wall thereof, said compartmenthaving a series of steam-outlets in the top, heating means, a-series ofreceptacles adapted to liest upon the top of the stove and pipeconnections between said receptacles and steamoutlets, said compartmenthaving` a passage in its wall in communication with the heating means,said passage being in open com- In unication with the oven,substantially as described. Y

2. The combination With a stove having a fire-chamber in the frontthereof, of a vertically-arranged boiler located above the same having aWater-compartment and an air-compartment therein, said air-compartmentincreasing in Width toward the top of the vertical compartment anddecreasing in depth and outlets in the top of the chamber, substantiallyas described.

3. The combination With a stove having an oven and a water-heatingcompartment, of a series of steam-discharge spouts leading from the topof said compartment, a series of receptacles adapted to rest upon saidstove and pipe connections between said receptacles and said spoutsloosely tting the same, the joints at the ends of the pipe being madesteam-tight by the Water of condensation, substantially as described.

4. The combination with a stove having an oven and a Water-heatingcompartment With a plurality of steam-discharge openings, ofcookingreceptacles detachable steam-tight connections between saidreceptacles and openings, and loose caps adapted to cover the openingsoutl of connection with a receptacle to prevent the escape of steam,substantially as described.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.

WILLIAM THOMAS PEARCE.
